i just got one of these from best buy this morning!  i don't seem to
have any trouble mounting the device.  it was formatted as a FAT 16

didn't mind being fdisk'd into an ext2 filesystem later).

so i can't say things look too differently...

do you have any other scsi devices on your system?  are you sure you're
trying to access the right one?  fwiw, this system is running debian
sid (home-rolled 2.4.20).

if you want to see my kernel config, i can send it to you off-list.
